Flashed v38 kaosfroyo and phone lasts 2 hours

[ChuckDee33]

I have no idea what Clockworks Recovery is or if I even have it. Actually, I just took the plunge into the whole rooting/recovery/flashing field a couple of days ago. So, I'm learning as I go with, of course, the help from great boards like this one. I also got a lot of advice from JonSuh.com | Tech/Web/Design/Stuff.

I did run into some trouble and a little panicking when I fiddled around with SetCPU. I originally had flashed CFSv8 after reading about battery issues and then I guess I over-overclocked with SetCPU (I think I had it at 76x max). It was freezing and rebooting randomly and then it got suck at the skateboarding screen :icon_eek:. I reflashed Kaos and dialed down the max to about 52x and it has been running fine but the battery still was depleting like a champ, I guess because reflashing Kaos deleted the CFS kernel.

I'll repost after I have some time to gauge the effectiveness of CFSv6, wiping the battery stats, and cycling through a couple of charges.

OK, I've run into an issue again with this whole process. I flashed CFSv6 on the advice given above in this thread and everything was OK. I also gathered that I need to reset the battery so I followed Rigby's steps: you have to fully charge with your phone off, wipe battery stats, let the phone drain until it dies and you can no longer turn it back on, charge fully while its off.

I was able to do all that and this morning when I booted the phone back up, it got stuck on the skateboards screen...just like it did after flashing CFSv8 the first time. (Might have been SetCPU causing this but not sure). Anyway, I tried pulling the battery and normal booting again but no luck. I reflashed Kaos v38 and it restored it just fine like I had to do previously. Phone runs fine now, except for Camera FCing and Gallery is sluggish.

The issue is, when I reflash the Kaos ROM, it resets the kernel and the CFSv6 one is gone, which negates everything I just tried to do with the battery overnight. Now the kernel is back to: 2.6.29 root@rackmount #3. Is this kernel OK to have or what? Why does flashing any version of CFS seem to cause boot issues? It very well may be a combination of things that are causing this. Any advice guys? I'm about to throw in the towel on the whole kernel modding adventure and just deal with whatever life the battery wants to give me.

you need to have cfs 6 flashed, im not sure why that is happening for you, flash cfs 6, and see how your battery life is with out recaling your batt. it will be 10x better than kf v38 by itself, then create a nand backup, later if you want to try a recal, and it messes up again you can just restore your nand

How do I create a nand backup? I've seen the term "Nandroid" but I'm not sure what that is or how to access it. Is it part of the recovery menu?

yes boot into recovery, look for backup/restore then choose, create nand backup, and wala, its like freezing your phone in time, when you restore a nand back up your phone will be exactly like it was the moment you shut it off to create it

BTW : u should always do a nand backup before u flash anything.

I all so wanted to add that, though its not advisable, you can calibrate with usage, it takes alot longer and isn't perfect but, if you flash the rom at 100 percent battery, and let run until its almost dead and then plug in, as often as possible, trying to stay away from short on the fly charging, your battery stats will eventually even out very close to a recal

I flashed with V38 then cfsv6 and it's been fine for me.

When you flash a ROM you flash the stock kernel as well. If the cfs6 works for you, you should save it on your phone, because every time you flash a new ROM you will have to reflash the kernel.

flashed v38 to my phone the other day, continuously had battery problems so i just decided to cut out the middle man and go back to v37 instead of bothering with the kernel, with my luck i'd do more damage to the phone than good, hopefully v39 will come out with a built in fix for the battery issue, if not any time soon does anyone have a fools guide to installing the better kernel? i really know nothing about the specifics of OS's and their workings.

Kernels flashing is exactly the same as ROM flashing. The difference is that only a portion of the OS gets updated instead of the whole thing. You don't lose any of your data or settings by updating the kernel. All you have to make sure of is that you wipe your Dalvik cache, system cache & battery stats when updating kernels.

Kaos v38 was the first ROM i flashed, and it was killing my battery. Nothing i tried helped ... i did cache wipes, battery tweak, upgraded the kernel.. i even flashed it twice cause i thought i did something wrong ... i finally scrapped it and switch to Conap's CELB ROM (xda developer) ... it's worked MUCH better for me.

conap makes a very nice rom, as do tazz and the rest of the xda devs, I've been using kf since v27 and has been my favorite, but I've tested others and the all have very good qualities. keep your eyes open for v39, with the b4 of kgb, and new git hub comments v39 shoulb be soon
